Vertical Force is a 1995 vertically scrolling shooter video game developed and published for the Virtual Boy by Hudson Soft in Japan and by Nintendo in North America. The player controls a starship, the Ragnarok, that must destroy a malfunctioning supercomputer on a human colony planet before it wipes out all of mankind. Gameplay is similar to Hudson's Star Soldier series, featuring power-up items that increase the player's abilities and parallax scrolling. The player can move their ship farther into the background to avoid enemies and obstacles in the way.
